DRILL + TAP COMBINATION DESIGN - Quickly drill and tap in one operation.
MAXIMUM EFFICIENCY - Eliminates separate drilling and tapping operations. Fast and easy; allows the drill to do the work.
MULTI-PHASE CRYOGENIC TREATMENT - Patented deep thermal cycle brings tools down to -300°F to alter and refine the molecular grain structure, relieve stress fracturing and increase durability & life.
TAPERED LEAD THREADS - Allow smoother transition between drilling and tapping.
SELF-CENTERING SPLIT POINT - 118° split point eliminates walking and wandering for precise hole positioning.
FLATTED SHANK CONSTRUCTION - Precision ground flats on the shank eliminate drill slippage and prevent damage to the drill and chuck.
SUPERIOR THREADS - The proper size hole is always drilled, providing ideal thread formation and superior thread strength.
SUPERIOR CONSTRUCTION - Premium "M" series alloy with ferro-gold surface offers reduced friction and long tool life.
VERSATILITY - Drills and taps into material thickness up to 2x the tap diameter.
